Stream Processing: Understanding Message Brokers

🚀Stream processing involves communication between producers and consumers via events.

🔄In-memory message brokers handle loads and maximize throughput, but messages can be processed out of order and lack durability.

📝Log-based message brokers store messages in sequential order, ensuring message order and durability.

🎥In-memory brokers are suitable for scenarios where message order doesn't matter and maximum throughput is required, like encoding videos on YouTube.

🔍Log-based brokers are suitable for scenarios where message order and durability are crucial, like processing sensor metrics or capturing database changes.

What is stream processing?

—Stream processing is the communication between producers and consumers through events.

What is the difference between in-memory and log-based message brokers?

—In-memory brokers offer maximum throughput but process messages out of order and lack durability, while log-based brokers ensure message order and durability.

When are in-memory brokers suitable to use?

—In-memory brokers are suitable for scenarios where message order doesn't matter and maximum throughput is required.

When are log-based brokers suitable to use?

—Log-based brokers are suitable for scenarios where message order and durability are crucial.

Can log-based brokers handle sensor metrics and change data capture?

—Yes, log-based brokers are suitable for processing sensor metrics and capturing changes in databases.
